The Elgato Facecam and the Logitech Brio 4K are both premium webcams, and both were sold to people who had outgrown a laptop camera. One of them is no longer sold. The Facecam's recorded product status is discontinued by the manufacturer, so it stays in this catalogue as a reference rather than as something to buy, and the decision in this comparison is now what the Brio 4K records that the Facecam does not.
The recorded decisive difference is focus behaviour. The Facecam records a fixed focus prime lens and software control over exposure and field of view. The Brio records autofocus, an adjustable field of view and infrared support for platform authentication. Neither can be judged from a specification list alone, so this page sets out what is recorded and what that does and does not tell a buyer.
Every value here comes from the specifications recorded against each product, with the manufacturer page it was read from. No camera was measured for this comparison, so there is no claim about image quality, autofocus behaviour in a dim room, or how either camera handles a moving subject.
What actually differs
Product status. The Facecam records its product status as discontinued by the manufacturer, and that note appears in its recorded feature list beside manual exposure control and the absence of a built-in microphone. The Brio records no such note and is the camera currently covered for purchase. This is the first difference, and it is a different kind of difference from the ones below.
Resolution. The Facecam records 1080p at 60 fps. The Brio records up to 4K at 30 fps and 1080p at 60 fps. The higher ceiling sits with the Brio, and both cameras can run the same 1080p at 60 fps, which is the mode most streaming and calling software is delivered in.
Focus. The Facecam records its lens as a fixed focus prime. The Brio records autofocus. A fixed lens suits a camera that stays in one position pointed at one seated person. Autofocus is the more forgiving arrangement when the camera moves or when more than one person is in frame.
Field of view. Both cameras record an adjustable field of view, with the Facecam specifying adjustable in software. The Facecam records a field of view angle of 82 degrees diagonal, while the Brio records 90, 78 or 65 degrees across three presets.
Infrared support. The Brio records infrared support as yes, and infrared authentication support appears in its recorded feature list, which is what allows Windows Hello style sign-in to use the camera. The Facecam records no infrared value at all, so it takes no part in that kind of authentication.
Built-in microphone. The Facecam records its built-in microphone as no, and the Brio records a dual omni-directional microphone with a range of up to 1.2 m. For a camera bought to replace a laptop camera, that difference can decide the purchase on its own.
Mounting. The Facecam records a monitor mount and a tripod thread, and a size of 58 by 80 by 48 mm without the mount. The Brio records no mounting value, so nothing can be said from the recorded data about how it attaches.
Who should pick which
If you are buying a webcam today, the Facecam is not the answer, because its recorded product status is discontinued. The Brio 4K is the camera in this comparison that is currently covered, and its recorded autofocus, its recorded infrared support and its recorded built-in microphone are the reasons to look at it.
The Facecam still earns a place here because its recorded specifications explain what manual control looked like in a camera at this price, and that is the standard the Brio is measured against. Its recorded manual exposure control and software adjustable field of view are worth understanding before buying a camera that decides exposure for you.
What this comparison does not settle
It does not settle price, because no price is recorded for either camera. It does not settle image quality, low light performance, or how reliable the autofocus is, because no camera was measured and no such record exists. It settles resolution, focus, field of view, infrared support, the built-in microphone, mounting and product status, which is enough to separate a discontinued 1080p camera recorded for reference from a 4K camera with autofocus that is still sold.
